ATTACHMENT FOR HANDLEBABS.

Application tiled February 1B, 1926. Serial No. 88,379.

This invention relates to improvements in attachments for handle bars ofbicycles or motorcycles and more particularly to a spring attachmentwhich acts as a shock ab- 'o sorber. Simplicity in construction,efficiency Ain use and durability are objects attained.

With the foregoing and other objects in view the invention consists inthe combination andarrangement of parts to be hereinlo a'ft'er fullydescribed, pointed out in the appended claims and illustrated in theaccompanying drawing which forms a part of this application and inwhich-- 4 Fig. `1 is a front view ot' the attachment, :partly insection, illustrating its application,

- and it is taken on line i-i of Fig. 2.

Fig. 2 is a side vien? and is taken on line 2-2 of Fig. 1. Fig. 3 is afragmentary vievv of the device illustrating 'the method of applying itto the base of the handle-bar.

Like reference characters denote corre sponding parts throughout theseveral views.

The reference numeral 1 denotes the hanthe cross bar 2, and 3 denotesthe steering post to which the head 4 is secured by the usual bolthaving the nut 5 at its upper end. Upon the steering post -bolt Iprovide a U-plate 6 and a link 7, both of said members being retained inposition by the said nut 5; said link 7 being connected by a chain 8 to`another link 9 that is car- 'ried` by a bar 10 secured by metal straps11 to ne; To the bar 10, at the ends thereof, the parallel threaded rods12ers secured and about each rod 12 is a coil yspring 13, one end o eachspring abutting a nut 14 arranged u on the inner end Uf 'lts red 12, theother en( ot 4o the spring being secured to a rod 15 carried bytheU-plate and disposed et right angles to said rods 12 and between thesame. To the said rod 15 springcoils 16 Iare secured also, said coilsencircling the aforesaid rods 12 and being secured thereto at one end.

Ordinarily the handle-bars are secured to the head el: by in nut 17which is so tightened upon the bitrii'cated end o'l' the head 4 thatrelative moveihent of the handlebars is prehowever, to so loosen this 18can be disposed prongs oft the head (i.

nut 17 that a Washer thereupon between the This will permit movement ofthe handlebars upon the' head 4 as a pivot in a vertical lane. Toprevent lateral movement of thc andle-bars I provide clamp collars 19pro# vided with ears 20 arranged upon opposite -sides of the head.

Vibration ot the handle-bars incident to travel over rough roads willnow be minimized and the shock absorbed by the expanlsion springs 13 andcoils 1G. Extreme movement of the handle-bars about the head #i will beprevented by the chain 8 that is con nected to the steering post boltand to the bar 10 which is fast to the cross bar 2.

What is claimed is 1. In combination, a steering post, a pair of handlebars connected to the steering post and capable of vertical rotatablemovement with respect to the steering post, a cross bur connected to thehandle bars, means secured to the cross bar to limit in one directionthe vertical movement of the handle bars, a pair of threaded rodsassociated with said cross bar, a third rod rigidly carried by thesteering post and disposed at right angles to said threaded rods, coilsprings connecting said threaded rods and the third rod, and springcoils connecting said threaded rods and said third rod, said springcoils beingr arranged upon the' opposite side of said third rod withrelation tosaid coil springs.

2. In combination, a steering post, a pair of handle bars connected tothe steering post y and capable of vertical rotatable movement withrespect to the steering post, a cross bar connected to the handle bars,means secured f to the cross bar to limit in one direction the verticalmovement of the handle bars, a air of parallel threaded rods rigidlycarried) bv said bar, a third rod rigidly carried by the steering postand disposed at right angles to said threaded rods and between the same,coil springs connecting said threaded rods and the third rod, andspring' coils connectingr said threaded rods and said third rod, saidspring coils being arranged upon thc opposito side of said third rodwith respect to said coil springs.

vln testimony that l claim the foregoing as my own I have hereto atiixcdmy signature.
